JOSEPH F. MUMFORD, OF PHILADELPHIA, PENNSYLVANIA.

SPECIFICATION forming part of Letters Patent No. 764,898, dated July 12,1904.

Ap licati fil d March 30, 1903. Serial No. 150,337- KNo model.)

To all 1071/0171, it may concern:

Be it known that I, J osnrrr F. MUMFORD, a citizen of the United States,residing in the city of Philadelphia. county of Philadelphia, and Stateof Pennsylvania, have invented new and useful Improvements in Machinesfor Manufacturing Brushes, which improvements are fully set forth in thefollowing-specification and accompanying drawings.

The object of my invention is to provide a machine for the manufactureof brushes which will automatically shape and compress aknot or tuft ofbristles or brush-fiber, the brushknot or tuft, as it is technicallytermed, being supported and automatically shaped. in a movablebrush-shaping cup, the said cup in its movements shaking and agitatingthe bristles or stock composing the brush and causing the end confinedtherein to assume a shape or contour similar to the interior of the cup,to compress the shaped brush-knot and trim the outwardly-extending endthereof, to apply a ferrule to the end of the trimmed brushknot and meltan adhesive and metallic alloy contained within the ferrule, so that thead hesive and alloy will envelop and bind the brush-knot containedwithin the ferrule, the brush being then ejected from the machine.

' Generally stated, my improved machine, considered in its entirety,comprehends, first, a plurality of movable automatic brush-shaping cups;second,mechanism to clamp and hold the shaped brush-knot; third,mechanism to trim the outward end of said shaped and clamped brush-knot;fourth, mechanism to convey cement supplied ferrules to the trimmedbrush-knot; fifth, mechanism to apply supplemented pressure to thetrimmed brush-knot; sixth, mechanism to apply the cement-suppliedferrules to the brush-knot and melt by heat the cement or adhesivetherein; seventh, mechanism to eject the formed brush from the machine;eighth, mechanism to advance the brush-shaping cups and brush-knotclamps and brush-knots; ninth, means to regulate the said advancingmovement; tenth, mechanism to lift and impart a succession of shocks tosaid brush-shaping cups. All the aforesaid devices are conjunctivelyoperated in the working of the machine.

Figs. 25 and 26 are perspective views of a ratchet-pawl-shiftingdevice in different positions. Fig. 27 is a sectional view of a portionof Fig. 14 on the dotted line Q Q, of Fig. 12. Fig. 28 is a sectionalperspective view of an adhesive and alloy supplied brush-ferrule.

In the organization of my improved machine, as shown in the accompanyingdrawings, the operative parts are mounted upon and connected with asuitable bed or plate, (designated A,) which may be of any convenientform, provided it serves to support the operative parts in position.

Referring to the drawings, A designates the table-top of the machine, towhich is secured a stand having two upright shaft-bearings 26 and 27,the bearings supporting the main driving-shaft 28. Mounted upon saidshaft 28 are two pulleys, one, 19, being fast, the other, 19, beingloose. On one end of shaft 28 a pinion-gear 20 is securely keyed.Secured to the table A is a stand and bearing 22, having'an extendedbracket 22, forming a bearing for a shaft 25, said shaft being furthersupported by a bearing 45 A large gear 21, having a hub,'is fastened bysaid hub to the end of shaft 25, so that said gear will mesh with thepinion 20, which is mounted in the bearings over it. Fig. 2 is a rearelevation of the driving-gear.

33 and 34 are similar stand-bearings, also secured to the table A, thestand 33 forming a bearing for one end of a shaft 29, the other endbeing journaled in the stand 22. 30 is also a shaft journaled in thebearings 34 and 54 (See Figs. 1, 17, 18, and 21.)

31 and 32 designate intermeshing mitergears on shafts 29 and 30.

24 designates a worm secured to the shaft 25, said worm meshing with aworm-gear 23, which is secured to the shaft 29, said wormgcar being overand above the worm 24, the function of said worm and gear being to im.-part motion to the shaft 29. (See Figs. 1 and 2.)

2 represents a vertical shaft having a bearing in the table A andoverhanging bearing 84, the bearing being partly cut away in Fig. 1, soas to show other working parts more clearly. The lower end of the shaft2 runs in the table A and hasa shoulder turned thereon to support saidshaft, a collar 8 being fastened to the portion projecting under thetable.

1 designates a large ratchet having teeth out at regular intervals inits face, the number, as shown inFig. 1, being eight teeth, said ratchetbeing further provided with a hub F, Fig. 5, which also forms aconvenient bearing for a pawl-lever 10.

11 is a pawl secured to the lever 10 by the stud-screw 13,'the pawlbeing held. against the ratchet teeth by the spring 11. (See Figs. 1, 4,and 25.)

17 represents an eccentric which is guided and supported by the largestud-bolt 14, said bolt being secured through the table A by the nut 14,the eccentric being driven by the gear 15, which meshes witha similargear 16, which issecured to'the driving-shaft 25, (see Figs. 1 and 4,)the. gear 15 having a long hub with an annular should er turned thereon,the gear-hub being forced into the eccentric sufficiently tight to turnsame.

17 designates a strap around the eccentric, to the extended end of whichis attached, by means of screws 18 the supplemental eccentric-rod 12,said eccentric-rod being also socured to the pawl-lever 10 by the stud13. (See Figs. 1, 4, and 7.) Aplate 17 is secured to the eccentric tokeep the strap in place by means of the screw 18, sufiicient play beinggiven for free working. (See sectional view in Fig. 7.)

The brush-shaping cups 7 7 a 7 b 7 c are supported and guided by theradial arms 8 8 8 8 which arms project laterally from and are a part ofthe hub C, which is fastened to the ratchet-shaft 2. The outer ends ofthe arms are provided with bearings having bosses thereon, through whichbearings the apertures or holes e 7) 0 (Z are bored and through whichapertures the cup stems move, the bosses being finished on the top orcup side, soas to form a convenient seat for the said cups. (See Figs.4, 5, 6, 8, and 10.) The bruslrshaping cups are each provided with aguiding-stem projecting from the bottom of each cup, which stems aredesignated as 1 1' 1 1 The stems are turned round and smooth to ashoulder on each cup, (designated 1 2 3 4,) the shoulders being alsoturned true and smooth, so as to seat neatly on the finished bosses ofthe arm-bearings. The cup-stems are also provided with the keyways a L 0d, and the arm-bearings have the keys 12 12" 12 12, screwed in the sidesthereof, so that the said keys will project laterally into the keywaysof the cup-stem sufficiently to keep the cups from turning around orsidewise. The bottom of the cup-stems are provided with the collars 5 67 X 8", which are riveted thereto, so as to support and retain theopposing springs {0" 0 m (See Figs. 4, 5, 6, 8, 10, and 21.) It shouldbe here stated that the cupstems have a free-working fit in the stemholein the supporting-bearings. The enlarged sectional view in Fig. 8 showsmore clearly the key 12 in the cup 7 the key 12" being screwed throughthe bearings 2 and projecting into the said keyway. The cupstem 1 isshown as having a shoulder on the bottom thereof, so as to permit thecollar 6 to be riveted thereto and lie flush to the bottom of the stem,the coil-spring 90 being placed on the stem, so as to exert'considerabletension against the collar and under side of the supporting-bearings 2and thus oppose the upward movement of cup-stem and cup, but actingreversely as means to draw the cup down again, so that the cup-seat 2will strike the top side of the boss, which forms its support, with asharp blow or impingement.

Secured to the shaft 2, but above the brushcup-supporting arms, is thehub D, having the four radial arms 3 3 3 3 projecting laterallytherefrom, the said arms being shorter than the cup-supporting arms andprovided on the top sides thereof with the finished bosses X to 1 thatis, two bosses on each arm, (see plan in Fig. 9)the said four armssupporting four pairs of brush-clamping levers, each boss supporting alever. (See Figs. 5 and 9.)

The brush-knot-clamping levers 5 5 5 5 5 5 5 5 with the small plaingears (Z to (Z 8 rigidly secured thereto, are fulcrumed and movepivotally on the shoulder-screws t to 2?, which are fastened into thebosses of the arms 3 3 3 3, so that the gears will intermesh in pairs,as in Fig. 1, the gears (Z (Z 8 on the levers gears (Z 2 (Z 3 on levers5 5, gears cl (Z 5 on levers 5 5, gears (Z 6 (Z 7 on levers 5 5,respectively. On the outer end of each clamping-lever a brushclamp issecured, and these are designated in the following order: thebrush-clamp 6 to the clamping-lever 5, clamp 6 to lever 5, clamp 6 tolever 5", clamp 6 to lever 5, clamp 6 to lever 5, clamp 6' to lever 5and clamp 6 to lever 5 clamp 6 to lever 5. (See Figs. 1, at, 5, and 12.)It will be seen that the clamping-levers 5 5, 5, and 5 extend inwardlyfrom the gears or pivotal point and have thereon the cam-rollers 9 9 9"9. The levers 5, 5", 5, and 5 also have short extensions inwardly fromtheir pivotal point ((lesignatedf" f f f) to these ends, and a portionof the opposite levers, the clampopening springs 10 1O 10 10 areattached. The brush-knot clamps, it will be seen in Figs. 1, at, and 5,are placed over and in alinement with the brush-shaping cups, so thatthey will be central with the cup centers, the said cups being shown inthis case to be of circular shape. The clamps are obviously of the sameform, but smaller. The brush-clamps are further provided with what Icall brush-collecting spurs or tangents, a pair on each clamp, in thefollowing order: clamp 6, tangents T '7; clamp 6, tangents 7 g 7; clamp6",

tangents T 7 clamp 6", tangents 7 7;

clamp 6, tangents T 7 clamp 6 tangents 7 7; clamp 6, tangents 7 7; clamp6*, tangents '7, (see Figs. 1, 4, and 5,) the tangents extendingoutwardly from the diametral line of the clamps, so as to embrace alltheloose brush-stock B, when the clamps are moved inwardly to close, andwhen closed the tangents will overlap. (See Figs. 1, 4, 5, and 21.) I

Secured to the table is a stand 40, said stand having the singlehorizontal shaft-bearing 39 and the lateral bearings 40 and 40 Avertical shaft 39 runs in these bearings. To the top end of this shaft amiter-gear 36 is secured and intermeshes with a similar gear 35, securedto the shaft 29, also secured to the shaft 39. Above the bearing 4O isanother mitergear 38, which intermeshes with and turns the gear 37, saidgear 37 being secured to the horizontal shaft 39, which runs in thesingle bearings 39 in the stand 40. On the inner end of the shaft 39"and beneath the stern of the brush-shaping cup a cam-carrying wheel 4:1is secured, said wheel having a plurality of cam-surfaces projectingfrom the face thereof, the said earn projections being adapted in theirrotation to alternately lift one of the brush-shaping cups when the cupis in vertical alinement therewith, thecam-surfaces contacting with thecollared end of the cupstem and raising said stem and brush shaping cupto the full height of said projections and causing the top of saidbrush-shaping cup to strike the under side of the stem of thebrushguiding ring 4 as shown in Fig. 5, the opposing tension of thespring X pulling the cup down again to the arm-bearing seat with a sharpblow or impingement. WVhen the cup-stem is released from the camprojection, the lifting and dropping movement thus imparted to the cupand stem will cause the knot of loose brush-stock B, confined withinsaid brush-shaping cup, to be agitated and settled to the inner shape ofthe cup. (See Figs. 4, 5, and sectional Fig. 8.)

The pawl-shifting lever 42 is fulcrumed on the shoulder-screw 42, whichis fastened to the upper side of the stand 12". On the under side of thelever end, projecting inwardly, a shifting roller 4:4" is secured, thesaid roller being adapted to contact and roll against the inner side ofthe ratchet-pawl 11 during a portion of its extreme inward movement andby the contact thus secured to keep the pawl from engaging theratchet-teeth for a definite number of its reciprocating movements, theretaining-spring 42, secured to the lever and stand, keeping the leverand roller 44' down and in operative contact with the said pawl 11,

roller 44 down to operative contact with said pawl again and hold samefor another definite period. These movements are illustrated by the 25and 26. In Fig. 25 the pawl-shifting roller 44 is shown as operatingagainst the pawl 11 and shifting said pawl from engaging a tooth of theratchet 1. Fig. 26 shows the pawl-shifting roller and lever lifted aboveand out of operative contact with said pawl, thus permitting theretaining-spring 11 to draw the pawl 11 into and engage a tooth of saidratchet and advance same to a definite point. (See Figs. 1, 4, 5, 25,and 26.)

The stand 45 is securely fastened to the table A, said stand having theshaft-bearing 45, supporting the driving-shaft 25. On the upright 45 ofsaid stand are two projecting shaft-bearings 45 and 45. A vertical shaft45 runs in the said bearings. On the bottom of said shaft is amiter-gear 45 which intermeshes with a similar gear 45, secured to androtating on the shaft 25. (See Fig. 14.) On the top end of the shaft 45which extends above the arm 45 a plain gear 46 is secured.

-(See Figs. 1, 12, 13, and 14.) The small vertical shaft 49 runs in thesingle vertical bearing 52, which is a part of the stand-upright 45,Figs. 14, 15, and sectional plan 27. A small gear 47 is fastened to theshaft and intermeshes with and receives motion from the gear 46, whichis fastened to the shaft 45, Figs. 14 and 15.

Over the gear 47 and on the shaft 49 is a shear-bearing lever 50, saidlever oscillating on the said shaft, which forms a convenient bearingfor the lever, the said lever having a long and short extension from itsoscillating center, the longest or inward end being adapted to support arigid brush-shear 50, Figs. 1, 12, 13, 14. Above the shear 50 are theguiding-grooves 50 and 50, in which reciprocates the top or memberingshear 50, (see section in Fig. 14; see Figs. 1, 12, 13,14,) the twoshears having a shearing or membering fit and overlapping each other.Securely fastened to the said shaft 49 is a small eccentric 49. Aneccentric-strap and link 49 works reciprocally on said eccentric, theend of the link 49 working on the shoulder-screw49, which is fastened inthe top of the shear 50.

On the shaft 45 above the lateral bearing 45 an eccentric 48 is secured.A link lever 48 is fulcrumed in another extension 45 of The inner end ofthe lever is provided with the yokes 48 and are in alinement with theeccentric 48, said eccentric being adapted to move the lever andlaterally oscillate same. (See Figs. 1, 12, and 13.) The short oroutwardly extending end of the shear-bearing lever is connected with theouter end of the yoked lever by the link 48 Figs. 1, 12, and 13, andworks freely thereon over the shoulder-screws 48 48 the moving eccentric48 imparting, through the lever 48 and connecting-link 48, anoscillating movement to the shear-bearing lever and shears, theinter-meshing gears 46 and 47 imparting motion to the eccentric 49 andlink 49" and reciprocating the shear 50 over the stationary shear 50,the shear-bearing lever 5O working freely on the shaft 49 and causingthe link and strap 49" to slip on the occentric 49 as said leveroscillates the shears across the brush-top, the shear 50 beingunderstood as always in motion and clipping all straggling hairs thatpass within the cutting edges of the said shears, as in Fig. 12. Thesection in Fig. 27 shows the position occupied by the shaft 49, whichextends through the bearing 52, the gear 47 having a long hub, whichprojecting well into the bearing forms a convenient support for itselfand the shaft 49, to which it is fastened, the said shaft having ashoulder thereon to give a broader hearing for the shear-bearing lever50 to oscillate freely, the eccentric 49 being secured above said.lever.

Secured to the table A is a vertical stand 53, said stand having alever-supporting arm 53 extending therefrom, the top of the stand beingadapted to hold and support a swinging bell-crank lever 55, the longestor inwardlyextending end of the lever being provided with a flat sideextension 55, the said extension forming a bearing to support on its topside a pair of ferrule-clamping levers 58" 58. On the short andoutwardly-extending end of said lever 55 a cam-roller 55 is secured.(See Figs. 1, 16, 17, and 19.)

A shaft and cam supporting stand 54 is secured to the table A andadapted to support the cam-shaft 30. An upright 54 extends verticallyfrom said stand and is provided with two lateral-shaft-bearings 54 54. Acam-shaft 54 runs in these bearings. A miter-gear 54 is secured to thesaid shaft and inter-meshes and turns with a like gear on the shaft 80.(See Figs. 1, 16, 17, and 18.)

A pair of small plain gears 58. 58 are secured to the ferrule-clamplevers 58" 58, said gears intermeshing and being fulcrumed and movingthe levers pivotally on the shoulderscrews 58" 58 which are fastened inthe top of said lever 55. (See Figs. 1, 16, and 17.)

On the short inwardly-projecting end of the clamp-lever 58 aferrule-clamp 58 is secured and likewise a clamp 58 on the lever 58, theclamps being of circular form, but not entirely encompassing thebrush-ferrule 61. (See Fig. 16.)

Between the outwardly-projecting ends of the clamping-levers 58 58 aspring 58 is placed, the spring being supported and guided by the curvedpin 58, one end of which is fastened in the lever 58, the other endmoving loosely through an aperture in the lever 58 it being extended bythe return 58, the function of the spring being to press the leversoutwardly and close the ferrule-clamps 58 58 sufliciently tight to gripand convey a brush-ferrule.

A lever 56 is fulcrumed and moves pivotally on a shoulder-screw 56,which is fastened in the stand-arm 53*. A cam-roller 56 is secured tothe outward or short end. A rotating cam 53" on the shaft 5 1 is adaptedto wipe against said roller 56" and cause the lever 56 to be pressedagainst the ferrule-clamp lever 58, so as to open the clamps whendesired, a spring 56 controlling and keeping the roller 56 at all timesagainst the cam. (See Figs. 1, 16, and 17.) In Fig. 1 the clamps areshown opened by the lever 56 pressing against the clam p-lever 58", soas to admit a brush-ferrule within the clamps. In Fig. 16 the said leverdoes not influence the clamps, which are closed over the ferrule 61 bythe spring 58 The subcompressing clamping-levers 59 59 have the smallplain gears 59 59 secured to the ends thereof and move pivotally on theshoulder-screws 59 59, the said screws and levers being secured to andworking on the under side of the extension 55 of the lever 55. A spring59 is secured to the inner sides of the levers 59 59, so as to keep thelevers apart when not otherwise influenced. On the end of the saidlevers the brush-subcompressing clamps 59 59* are secured, the clamp 59on the lever 59, the clamp 59" on the lever 59.

(See Fig. 20.)

A lever 57 is fulcrumed and moves pivotally on the shoulder-screw 57 andhas a clamplever roller 57 on the inner end thereof. A cam-roller 57 isattached to the outer short end of said lever and is adapted to contactwith a rotating cam 53 said cam being secured to the shaft 5 1 beneaththe lateral arm 51" of said stand-upright 54:, a spring 57 keeping thecam-roller 57 always in contact with the cam 53, (see Figs. 1, 16, 17,and 20,) the function of said clamps being to subcompress the brush-knotend B in the cup 7 so that the ferrule 61 may be applied without beinginterrupted by the brush-stock.

The stand 60 is secured to the table A. To a lateral extension thereof60" and brace 60 a ferrule-supplying pipe 60 is secured, the pipe havinga longitudinal slit or peep-opening through a portion of its length, thesaid pipe being adapted to convey a series of verticallyarrangedbrush-ferrules 61, which will gravitate loosely through said pipe bytheir own weight, the ferrules being supplied with an adhesive cementand metallic alloy. A circular ferrule-receiving plate 60 is pivoted onthe shoulder-screw 60 which is fastened to the top of the extension 60of said stand, a spring 60, secured in said extension by the screw 60controlling the inward movements of the receiving-plate 60, the saidplate being adapted to swing under the supply-pipe and ferrulescontained therein and receive and support said ferrules when they arepermitted to drop from the supplying-pipe, (see Figs. 1, 16, and 17,)the projection on the lever pushing the plate outwardly and from theline of movement of said lever 55.

A cam-roller 55 is secured to the short outwardly-projecting end of thelever 55. A cam 53, secured to the shaft 54*, is adapted to rotate inoperative contact with the said roller 55" and move said lever andsupported parts inwardly toward the shaped, clamped, and trimmedbrush-knot in the shaping-cup 7 a spring 55 secured to the standprojection 53 causingthe lever and associated parts to recede from thesaid brush-knotB after the ferrule has been applied. Y

A ferrule support or "retainer 63, as I term it, is secured to the topside of thelever extension 55 and moves therewith, the said retainerbeing a narrow strip which projects above the ferrule-clamp levers, sothat its top side will pass under the bottom ferrule in the supply-pipe60 nearly all of which ferrule is confined within the said supply-pipe,the said ferrule being in this view designated as 61. The view in theplan in Fig. 16 shows the retainer 63 as having been advanced by theinward movement of the lever 55, so that it has passed entirely underthe ferrule 61 and beyond the gravitating line thereof, the cement inthe ferrule being cut away to show more clearly the position of theferruleretainer under said ferrule. The view in Fig. 17 which is a sideelevation of Fig. 16, shows the position of the retainer 63 under theferrule 61". Now the ferrule 61, which preceded the retained ferrule 61,having been allowed to drop to the ferrule-supporting plate 60 in thesaid Fig. 17, the ferrule-clamps 58 58 are shown as having gripped thesupported ferrule and are ready to convey the said ferrule to thebrush-knot, as shown in the plan in Fig. 1, the retainer being movedaway from under the said ferrule in the outward inovement of the lever55 until it passes beyond the ferrule-supply pipe, and thus permits thenext ferrule in line to drop to the ferrule-receiving plate, which hasbeen returned to its position under the ferrule-pipe and ferrules, as inthe view in the plan of Fig. 1. In the view in Fig. 17 the ferrule 61 ispartly cut away at the top portion, so as to show the position of theretainer 63. The view in the plans in Figs. 1 and 16 does not show theabove-described parts so clearly as the view in the elevation Fig. 17.

The stand 65 is secured to the table-top A, said stand being providedwith the bearing 69 to support the cam-shaft 30, the stand also havingsuitable bearings to support devices to apply a conveyed brush-ferruleto a brushknot and to support devices to eject a brush from theshaping-cup and the machine.

A curved lever 62*is fulcrumed and moves pivotally on the shoulder-bolt6A, which is secured to the stand 65, the short or lower end of thelever being provided with a cam-roller 62 and adapted to roll against arotating cam 68, which is secured to the cam-shaft 30. On the long andupper end of the lever a combustion-chamber 62 is secured, said chamberhaving a gas-burner 62 projecting downwardly therein through thesupporting-boss 62 on the top of said chamber, the chamber having alarge opening 62 in the front wall thereof. A flexible gas-pipe 62 issecured to the top of said burner and leads the gas into said burner,the holes 62 in the side of the burner 62 supplying air to mix with thegas in its downward flow through the burner-inlet 62, the saidchamber-opening 62 also supplying air to support combustion and as meansto light the said burner. (See Figs. 21 and 23.)

On the bottom of the chamber 62 and projecting centrally therefrom is abrush-adhesive and alloy-melting tool 62 and adapted to be insertedwithin the brush-ferrule 61, which is supported by the conveying-clamps58 58, (see section in Fig. 21,) the said ferrule having therewithin asupply of adhesive cement and metallic alloy and just sufficient tosecure a brush-knot. The base 62 of the chamber 62 is used as a means tocontact with and press the brush-ferrule 61 down around the brushknot Buntil it rests upon the subcompressingclamps 59 59, the heat from themelting-tool 62 melting the said adhesive cement or alloy within theferrule, the melting-tool 62 pressing the fused material 61 61 downaround the brush-knot B, the spring 77, secured to the lever-arm 62 andstand 65, lifting said lever and causing the combustion-chamber andmelting-tool 62 to recede upward and away from the ferrule 61. (SecFigs. 21,23, and 28.) The view in Fig. 21 shows the melting-tool 62 inaction in the ferrule 61, the cam 68 having actuated the lever 62, thusdepressing the chamber and melting-tool and applying said ferrule andmelting therein the contents. In Fig. 23 the lever 62, being releasedfrom the earn, the spring 77 has lifted the chamber and melting-toolfree from said ferrule.

Turning on a shoulder-screw 83 is a brushejector lever 71. Secured tosaid lever and working on said screw is a small plain gear 72, saidscrew being fastened to the lateral arm 66 of the stand 65. Fulcrumedand moving on the shoulder-screw 7 1, which is fastened in the lateralarm 75 of said stand 65, is a gearsector 73, the lower plain end of saidsector having a cam-roller 76 affixed thereon and adapted to rollagainst the cam 70, which is secured to the shaft 30, the said sector 73intermeshing with and turning the gear 72 and ejector-lever 71. (SeeFig. 23.) On the end of the lever 71 is a bell-crank spring-controlledbrush-ejector clamp 7 9, said clamp being pivot all y mounted on. theshoulder-screw 78, which is fastened to said lever. A spring-supportingpin 81 is secured to the part 78 of the ejectorclamp,said pin Workingloosely through the lever 71 and supports the clamp-springSl. (Secenlarged view in Fig. 24:; see also Figs. 1, 21, and 23.) Threepositions are shown of the ejector. The plan in Fig. 1 shows the clampas having received and gripped the brush, which has been advancedthereto, as indicated by the dotted lines of the clamps and brush-cup.The view in Fig. 21 shows the position occupied by the clamp with thebrush clamped therein and ready to be lifted from the cup. The movementdescribed by the ejector and brush is shown by dotted lines in the saidview. In

Fig. 23 the lever 71 is shown in full lines as having lifted the brushfrom the cup and carried the same through an orbit, (shown by the dottedline,) the clamp 78 striking a projecting angular boss 67 on the lateralstand-arm 67, the contact opening the clamp 79 and releasing the brush,which'may fall into a convenient receptacle, (not here shown,) thespring 66, secured by the screws 65 65 to the stand and sector,returning the empty clamp to the position shown in Fig. 21. The arm 67is cut away in the plan in Figs. 1 and 24:, but is seen in full in Figs.21 and 23. The plan of the combustion-chamber is cut away in Figs. 1 and16, so as to show more clearly the brush-cup and parts as well as theferruleconveying devices. In Fig. 22 the plan of the chamber 62 and apart of the lever 62 is shown.

The operation of the machine in detail is as follows: Motion iscommunicated to the various devices by means of the driving-gear 19,19,20, 21, 23, and 2 1. The eccentric 17 will give a reciprocating movementto the pawl 11, which engaging a tooth of the ratchet will impart anintermittent rotary movement to the ratchet-plate and as said plate isfastened to the vertical shaft 2 will cause this shaft and all partsattached thereto to rotate. The machine being in motion, a supply ofbristles is placed by hand in the brushshaping cup 7, (see Fig. 1,) saidcup occupying a point in the front part of the machine, the bristlesbeing further guided and supported by the brush-ring 1 It may be herestated that the brush-shaping cups areall larger than the knot ofbristles will be when made up into a brush, the reason for this being togive the bristles freedom to settle in the cup and assume a desirableform or contour on the end. The cup and brush-knot will now be movedaround the machine to the point occupied by the cup 7. Now at thispoint, as well as at all four operative points of the machine viz., thepoints occupied by the brush-shaping cups 7 7 7 7 -it is desirable togive the knot of bristles B treatment in the several stages necessary toform a brush. These treatments will necessitate a pause in the action ofthe pawl on the ratchet-wheel. This pause or rest is obtained by thepawlshifter 4: 1", Figs. 1, 4, 5, 25, and 26, the pawl in its inwardmovement wiping against the roller .IOO

44 and being held there long enough to pass the ratchet-tooth, which itwould otherwise engage. In regulating the movement of the shafts 29 and30 I use a device similar to the one described in my PatentNo. 711,065,dated October 14.. 1902; but in this machine I only use one worm gear,23, the brush-shaping cups and appendages being moved once during acomplete revolution of the-said gear. The cam 41 on shaft 30,controlling the movement of the pawl-shifter lever 12, will raise theshifter 4 1 at a period in the revolution of said cam, so as to allowthe pawl 11 to drop into and engage a tooth in the ratchet 1. The periodduring which said shifter is raised will allow the pawl to engage saidratchet twice, and as the ratchet is provided with eight teeth outequally distant it is obvious that the action of the pawl on the ratchetwill move the cups and brush-clamps and brush-knot a quarterturn only,respectively, from 7 to 7, 7 to 7 7" to 7", and 7 back to the point 7,where the cup '7 will be free to receive a new supply of bristles B, theshifter dropping in place after the pawl has engaged the two successiveteeth in the ratchet and preventing any further movement of said ratchetuntil the cam 14 in its revolution shall again lift the pawl, allowingsame to again engage the teeth thereof, these movements being repeatedonce during the revolution of the gear 23 on shaft 30, the pause thussecured allowing time for the devices to operate on the bristles in theseveral cups. (See Figs. 1 and 4.) WVhile the cup 7 is at rest thebristles B confined therein are subjected to a series of vibratingshocks. This is accomplished by the cam-wheel 4:1, the cams of whichwipe against the bottom of the brush-cup stem 1, alternately lifting thesaid cup. The spring ra drawing the cup down so that the shoulder 2 ofthe cup will impinge against the support 2 with a sharp blow or impact,these little and rapid blows will cause the bristles B to settle andassume a shape similar to the interior of the cups bottom, the brushknot or tuft always being placed in the cups with the flag or taper endsdown, the root ends extending above the cups,so as to be trimmed.cemented, and bound within a ferrule. The sectional view in Fig. a ofthe brush-shaping cup 7 gives a general idea of the interior of the cupused to form a round nose on a brush. It is obvious, however, that thecups can be made of any of the usual shapes of brushes-round, flat, oroval. In either case the brush-clamps, would be of the same shape as thecup. The cup 7 with the brush-knotnow shaped, will-be moved, by theaction of the pawl being released, from the shifter to the positionoccupied by the cup 7 In the movement of the cup from 7 to 7 the knot ofbristles B will be subjected to compression by the brush-clamps 6 6,Fig. 1, the said clamps being closed around the brushknot 8, said clampsbeing closed by the roller 9 wiping against the rigid cam 8, the gears(Z (Z acting together, this compression taking place in the movement ofthe cup 7 away from the cam-wheel 11, the compression being completebefore the pawl has made one forward movement of the ratchet, it beingnecessary to compress the bristles or brush-stock quickly; otherwisethey would drop into the larger space of the cup and thepreviouslyformed nose would be ruined, the second engagement of the pawlmoving the clamped brush-knot and supporting devices to the positionoccupied by the cup 7 (See Figs. 1, 4, 12, and 13.) In cupping andshaping the knot of bristles B the outer rows of bristles, by reason ofthe rounded contour of the interior of the brush-shaping cup, willnaturally project above the center of the knot. (See Fig. 1.) It isdesirable that these projecting ends, and, in fact, all straggling end,shall be trimmed even with the center of the knot. This is done by meansof a brush-shearing device situated in the rear of the machine. Thestationary and reciprocating shears 5O 50 oscillating on the plate 50over the tops of the bristles will shear the top of said knot perfectlyeven with the center of the knot, the shears being oscillated a numberof times over the top of said knot while at rest in the cup 7 In Fig. 1the shears are shown at one extreme of movement. In Fig. 12 they areshown as being centrally over the brush-knot in cup 7 (See Figs. 1, 1,12, and 13.) Fig. 12 shows the manner in which the shears operate byshearing all the bristles coming within the shearing-blades 50 and 50,the arrows indicating the direction of movement. The trimmed end of thebrush-knot is now moved forward to the position occupied by the cup 7where an adhesive or alloy charged ferrule 61 will be placed over thebrush-knot and the cement in said ferrule melted or fused, so as toenvelop and bind the root ends of the brush-knot confined within saidferrule. The application of the ferrule 61 to the bristles B is madebythe ferrule-clamps mounted on the swinging lever 55. The ferrules 61,which have been previously supplied with a brushbinding adhesive andmetallic alloy of low fusing-point, are placed in the supply-pipe whichis of convenient length or height. The ferrules fitting loosely withinsaid pipe will fall by gravity onto the ferrule-plate 60", thesupply-pipe having a small longitudinal opening, so as to see the supplyof ferrules inside of the pipe. In Fig. 1 the ferruleclamps are shown asbeing directly under and in line with the ferrules 61 in thesupply-pipe, and the clamps being opened a single ferrule is shown ashaving dropped into the clamp by reason of ferrule-retainer 63 havingpassed back beyond the line of the ferrules, the single ferrule beingpushed down by the weight of the ferrules above it, the'ferrule-platereceiving and holding the ferrule until the clamps 58 are allowed toclose and grip the ferrule, the ferrule-plate being pushed outward andaway by the outer end. of the lever. (See Figs. 1 and 16.) The conveyedferrule is next pressed down over the compressed brush-knot until thebottom of the ferrule reaches the clamps 59 59*, the pressure thereceasing, as that places theferrule over the brush-knot to the pointrequired. The pressing of the ferrule over the knot is done, as beforestated, by the combustion-chamber base 62, the melting-tool 62 at thesame time penetrating the interior of the ferrule and contacting withand melting the combination of adhesives contained therein and pressingthe same down around the brushknot end, so that it will envelop theportion of the knot confined within the ferrule and bind it therewithin,the adhesives employed being cement and metallic alloy, either singly orin combination, and is conveniently placed in the ferrules before theyare put into the supply-pipe. The brush is then ejected from the cup andmachine, the movement of the cup from the ferruling and cement-meltingdevices bringing the ferrule to the ejectorclamps, which will lift thebrush free from said cup and throw it from the machine. The brush-cupnow emptied and having been advanced to the starting-point 7 is ready tore ceive another brush-knot and repeat the operation just described inall of the four cups, so that there will always be one cup to besupplied with a brush-knot, one cup vibrating or shaking and shaping aloose brush-knot, one cup having a clamped, shaped brush-knot beingtrimmed, and one cup having a ferrule placed over'a trimmed brush-knotand having the cement melted thereon, the operations being carried onsimultaneously throughout the machine.

Obviously my improved machine may be constructed with a greater or lessnumber of brush-shaping cups and brush-clamps and the shapes and sizesof the cups may be made to conform with the usual or preferred shapes ofbrushes in usethat is, round, fiat, or ovalwithout departing from theprinciple of the invention.
